Question

Calculate the surface area of the rectangle prism in the picture​

Answer 1

Answer:

252

Step-by-step explanation:

Formula

2wl + 2lh + 2hw=

2( 12 x 6) + 2( 12x3) + 2 ( 3x 6)

2(72) + 2(36) + 2(18)=

144 + 72 + 36= 216 + 36

252

Answer 2

Step-by-step explanation:

l = 12 in

w = 6 in

h = 3 in

S. Area = 2 (lw + lh + wh)

= 2 (12 × 6 + 12 × 3 + 6 × 3)

= 2 (72 + 36 + 18)

= 2 × 126

= 252 in^2
